SPECIFICATION forming part of Letters Patent No. 706,989, dated August 12, 1902.

Application filed January 28. 1902. Serial No. 91,570- (No model.)

To (LZZ 1071 0771 it may (Jo/warn.-

Be it known that I, RICHARD A. MYERS, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio,haveinvented certain new and useful Improvements in Twine-Spinning Machines, of which the following is a specification.

My invention relates to an improved nipping and forming mechanism in a spinningmachine through which the sliver is fed to the usual twisting mechanism, consisting of the, flier and capstan, not necessary to be shown in the drawings.

The features of myinvention are more fully setforth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is aside elevation of my improvement. Fig. 2 is a rear end view of Fig. 1. Fig. 3 is a top plan view of my improvement with the top sections of the nipper and the former detached. Fig. an a section on line a- 00, Fig. 2. Figs. 5 and 6 are perspective views of the nipper-sections. Figs.'7, S, 9, and 10are perspective views of the top and bottom sections of modified forms of the forming device. Fig. 11 is a vertical section enlarged, showing the forming-channel through the top and bottom sections of the former when placed together. Fig. 12 is a detached sectional view of the nipper mechanism.

My invention has for its object the production of a cheap and simple mechanism for feeding the sliver to the twisting mechanism of a spinning-machine in which. devices are embodied for limiting the twist of the yarn or twine in the throat of the receiver, so that the twisting of the sliver commences at a point just beyond the receiver and the yarn is pressed and drawn through aforrning-duct leading to the flier. The twisting of the yarn in this channel as it is fed longitudinally through the channel has the eii'ect of reduc ing the yarn to a uniform diameter. The yarn in passing to the flier is inclined to bunch up, tangle, or agglomerateat intervals, which inequality and defects go into the twine, so as to destroy the homogenous effectthereof. Therefore the result, broadly speaking, of my device is the production of a more uniform and homogeneous grade of twine. Another advantage is that the device automatically removes the tangling, bunching, &c., of the sliver with improved efficiency resulting from the use of the combination of mechanical elements herein claimed as invention, sothat the machine operates more perfectly than prior devices in this particular.

A represents the standard suitably supported on the spinning-machine, forming the basis of the attachment of my improved devices. i I

B represents a funnel-shaped receiver converging to a receiving-throat B, and this receiver issecnred by bolts 1 2 to the said standard A. (See Figs. 2 and 3.) This receiver is provided with an open shaft or nipper seat extending through the same in vertical plane transversely to the throat B. (See Fig. 3.) 0 represents the two-part nipper fitting within said shaft, consisting of a lower section Z), which section is inserted in the said shaft and seats upon the end of the adjusting-screw e, screw-threaded into a log d, extended from the said standard A. By this means the nipper may be raised up and down for adjustment. This lower section b is provided with the bifurcated beveled limbs b b, forming between them the slot 31 11 represents a throat in this sectionb.

0 represents the upper section of the twopart nipper, which is substantially triangularshaped and seats with the recess formed bythe bifurcated beveled limbs b b" of the lower section b, the apexc of the said upper section passing through the said slot 19 of the lower section, as shown in Fig. 4. 0 represents a throat in the under side of this section 0. When the nipper-sections are in position, the throat proper, 0 b registers with the throat formation B of the receiver, forming a continuation thereof, which converges to the duct of the forming mechanism to be hereinafter described. The point e of the said apex c is the essential nipping feature, as it impinges squarely upon the shouldera. of the section b. The upper section is preferably weighted and seated simply by gravity in the lower section, and consequently yieldingly supported in position. A spring could be substituted for the Weight.

D represents two frame-plates attached to the standard in vertical parallel planes, between which is secured the forming device. The forming devices are constructed as follows, and consist of an upper section F and a lower section G, having teeth H projecting from the opposing faces of said sections, so as to intermesh telescopically. The lower section is'provided with the bolt or pin holes 3, and the plates D with corresponding pinholes for securing the lower section in position by 'pins, 4. That portion of the plates D which extends above the teeth of the lower section forms a.housing in which the upper section is telescopically supported. The middle of each tooth has a notch I formed therein, so that when the sections are placed together with the teeth engaging telescopically the inner extremities of the said notches I are alined to form the formingduct J. (See Fig. 11.) Y

K represents two brackets projecting-from the standard A parallel with the plates D.

L' represents a stirrup straddling the plates D, having upturnedhook ends engaging under the brackets K. M represents a stem passing through the said stirrup. N represents a spring coiled around said stem and engaging against thebridge of the stirrup at the top, and at the bottom engaging against an adjusting-nut, the bottom end of the stem being screw-threaded into the top of the top section F of the forming device. It is readily apparent that when the stirrup is placed in position as shown in Fig. 2 the top section is held to its position by compression of the spring and willgyield to excessiveinequalities of the sliver passing through the duct J. The last tooth H of the lower section of the former engages with the shoulder II of the upper section. At the other end of the former the shoulders H of the two sections engage one another, so that when the sections are placed together these abutting shoulders form stops limiting the depth of intermeshing of the teeth of the opposing sections. Thus the sections of the former are prevented from engaging one another to a sufficient depth to destroy the aline-' ment of the forming-duct J. The particular construction of the former shown in Figs. 9 and 10 is preferred,,the teeth being inclined from the opposite sides of the former toward the center in the direction of the travel of the sliver through the duct J, so as to offer the least possible resistance thereto.

Mode of operation: It will be seen that the throat of the receiver, the continued throat formation in the nipper, and the formingduct in the former are all three in alinement, so as to form. a single continuous straight passage-wayinto the twisting-machine. The

sliver is impinged between the nipper-point c and the abutting shoulder a of the nippersection b, so thatthe twists imparted to the twine by the capstan and flier begin at this point and the sliver is turned and fed alonga confined passage l, formed in the shoulder H of the former-sections, and the duct J,

formed by the notched teeth of the formersections. In the particular form shown in Figs. 9 and 10 the teeth of the lower section are open at the bottom, so that the particles of sliver and dust which are combed or removed from the yarn drop down between these teeth, and thus do not accumulate in the machine.

Having described my invention, I claim- 1. In a twine-spinning machine the combination of a funnel-shaped receiver converging to a threat, a two-part nipper, the lower section having bifurcated limbs, the upper section fitting and engaging between said limbs telescopically in vertical plane, a throat and anipper-point formed on the opposing surfaces of said nipper-sections, substantially as specified. l

2. In combination with a twine-spinning machine, a funnel-shaped receiver having a converging throat, a seat formed in said receiver transversely to said throat, a lower nipper-section adj ustably supported in said seat, said section having two upwardly-extended, beveled limbs, an upper nipper-section yieldingly and detachably engaging with said lower section telescopically in vertical plane, a throat formed between the meeting surfaces of said sections, the said upper section beingsubstantially triangular-shaped, having the apex projected between the said limbs of the lower section, and a nipper-point formed on the lower end of said apex adapted to impinge upon the sliver, substantially as specified.

In testimony whereof I have hereunto set my hand.
